Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and specifically to a municipal power distribution cabinet installation and fixing device. Background Art

[0002] A distribution cabinet (also known as a distribution box) is an important device for distributing electrical energy in a power system. It is primarily used at the end of a power system and is responsible for safely and efficiently distributing electrical energy to various electrical devices. A distribution cabinet typically consists of a variety of components, including switchgear, measuring instruments, protective devices, and auxiliary equipment. These components work together to control, protect, and monitor the power system.

[0003] When the distribution cabinet is in use, it needs to be transported to various municipal outlets and then fixed to ensure the stable operation of the distribution cabinet;

[0004] For example, the utility model patent with announcement number CN217769202U specifically discloses a quick installation and fixing structure for a distribution cabinet. When in use, the patent first clamps and installs a support frame bar in the support frame at the bottom end of the distribution cabinet, then sets a shock-absorbing component at both ends of the support frame bar, and uses fixing screws to fix the lifting frame bar and the support frame bar to complete the installation. When in use, the vibration generated by the distribution cabinet squeezes the lifting frame bar to slide vertically in the bottom plate, thereby squeezing the support spring to deform and absorb excess vibration, thereby being able to fix and support the distribution cabinet, ensure the stability of the distribution cabinet during installation, improve the buffering effect, and facilitate quick disassembly and replacement;

[0005] During the implementation of the above patent, a large number of bolts are needed to fix the distribution cabinet. Although this can increase the stability of the distribution cabinet, a large number of bolts require workers to install for a long time, and the bolts also need to be loosened when disassembling. If the number of distribution cabinets is small, this operation will not add much extra time. However, when a large number of distribution cabinets need to be configured in the municipal area, the tightening and loosening operations of the above bolts will consume a lot of time, thereby delaying the progress of the work. Therefore, it is necessary to provide a municipal distribution cabinet installation and fixing device to solve the above problems.

[0043] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0044] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0045] like Figure 1-Figure 2 As shown, the present application provides a municipal power distribution cabinet installation and fixing device, including a power distribution cabinet 1, wherein the power distribution cabinet 1 has a wheel body 11, so that the power distribution cabinet 1 can be moved to a position where it needs to be installed under the action of the wheel body 11;

[0046] In order to fix the power distribution cabinet 1, the wheel body 11 can adopt a universal wheel with a self-locking function, so that the power distribution cabinet 1 can be initially fixed by the self-locking function of the wheel body 11;

[0047] In this application, the height of the power distribution cabinet 1 is relatively high, so the stability of the power distribution cabinet 1 cannot be guaranteed by the self-locking function of the wheel body 11 alone. In order to further reinforce the power distribution cabinet 1, Figure 3As shown, square grooves 12 are provided on all four sides of the bottom of the power distribution cabinet 1. A cantilever mechanism 2 is installed in the square groove 12. The cantilever mechanism 2 is used to extend the bottom of the power distribution cabinet 1 in all directions, so that auxiliary fixing devices can be added at the extended position to improve the force position of the bottom of the power distribution cabinet 1, thereby making the power distribution cabinet 1 more stable.

[0048] like Figure 3-Figure 5 As shown, the cantilever mechanism 2 includes a connecting frame 21 fixedly installed inside the square groove 12, and the connecting frame 21 can be connected to the power distribution cabinet 1 as a whole by welding. At the same time, the interior of the connecting frame 21 is hollow and forms a mounting cavity (not shown in the figure). At the same time, a cantilever 22 is slidably arranged in the mounting cavity, and the cantilever 22 has a sliding end (not shown in the figure) that slides with the mounting cavity. Therefore, the cantilever 22 can be moved closer to or away from the power distribution cabinet 1 by sliding the sliding end in the mounting cavity. In the present application, the position of the cantilever 22 close to the power distribution cabinet 1 is defined as the storage position, and the position of the cantilever 22 away from the power distribution cabinet 1 is defined as the fixed position. Therefore, the cantilever 22 can be stored, and when the power distribution cabinet 1 needs to be fixed, the fixing device can be installed on the cantilever 22. At this time, the cantilever 22 is at a position away from the power distribution cabinet 1, thereby making the fixation of the power distribution cabinet 1 more stable;

[0049] At the same time, a limit frame 211 is fixedly provided at a position of the connection frame 21 away from the power distribution cabinet 1. The limit frame 211 forms a constriction. At the same time, a limit portion (not shown in the figure) is fixedly provided at the sliding end. The limit portion is suitable for being limited by the limit frame 211 to prevent the cantilever 22 from slipping out of the connection frame 21.

[0050] like Figure 3 As shown, a limiting mechanism 3 is provided between the cantilever 22 and the power distribution cabinet 1. The limiting mechanism 3 is used to fix the cantilever 22 in the storage position. The limiting mechanism 3 includes a first hook 31 fixedly mounted on the cantilever 22, and a second hook 33 fixedly mounted on the power distribution cabinet 1. A chain 32 is mounted on the second hook 33. When the cantilever 22 is close to the power distribution cabinet 1, the other end of the chain 32 can be hooked on the first hook 31 to fix the cantilever 22.

[0051] It should be noted that when the cantilever 22 is in a fixed position, a heavy fixing device is installed on the cantilever 22, so that the cantilever 22 will not move arbitrarily even if it is in a free state. Therefore, when the cantilever 22 is in this position, there is no need to perform additional fixing on the cantilever 22;

[0052] At the same time, two sets of clamping seats 23 are installed on the cantilever 22, and the two sets of clamping seats 23 are respectively arranged at the two ends of the cantilever 22. A screw 24 is threadedly connected to the clamping seat 23, and a knob 25 is installed at one end of the screw 24. At the same time, a pressing head 26 is fixedly installed at the other end of the screw 24. When installing, the knob 25 can be rotated to make the screw 24 close to the cantilever 22, and the cantilever 22 is clamped by the pressing head 26, thereby fixing the two sets of clamping seats 23 on the cantilever 22;

[0053] In order to connect the fixture, such as Figure 2-Figure 3 and Figure 5-Figure 6 As shown, a hanging mechanism 4 is installed on the cantilever 22, and the hanging mechanism 4 includes a connecting arm 41 fixedly installed on the inner side of the clamping seat 23. Two sets of symmetrical connecting beams 42 are fixedly installed between the two sets of connecting arms 41. There is a gap between the two sets of connecting beams 42, and a limiting groove 43 is formed. At the same time, an installation gap is formed between the top surface of the connecting beam 42 and the bottom surface of the cantilever 22.

[0054] A quick release mechanism 5 is slidably disposed within the limiting groove 43. The quick release mechanism 5 includes a quick release barrel 53. A matching block 54 is fixedly mounted on the side of the quick release barrel 53. The bottom of the matching block 54 is lower than the bottom of the quick release barrel 53. The matching block 54 is adapted to cooperate with the limiting groove 43, so that the quick release barrel 53 can be clamped into the limiting groove 43 through the matching block 54 and located in the installation gap.

[0055] At the same time, the connecting beam 42 is composed of high sections 421 at both ends and a low section 422 in the middle. The low section 422 and the high section 421 are both arranged horizontally, and there is a smooth arc transition between the two. Therefore, the bottom surface of the quick-release cylinder 53 can be inserted from the high section 421 into the connecting beam 42 and pushed into the low section 422, thereby allowing the quick-release cylinder 53 to slide stably into the low section 422 and remain in the position of the low section 422.

[0056] The quick-release barrel 53 has a through-groove 56 extending therethrough, and a partition 55 is provided inside the through-groove 56 , thereby dividing the through-groove 56 into an upper groove and a lower groove by the partition 55 ;

[0057] like Figure 7-Figure 8 As shown, a first spring 52 is fixedly installed in the upper groove of the quick-release cylinder 53, and a contact cover 51 is fixedly installed on the upper end of the first spring 52. Therefore, when the quick-release cylinder 53 is pushed into the connecting beam 42, the contact cover 51 is always in contact with the bottom of the cantilever 22 due to the action of the first spring 52. Therefore, the quick-release cylinder 53 can be clamped by the action of the upper and lower bottom surfaces of the installation gap. In addition, after the quick-release cylinder 53 is installed, the first spring 52 is always in a compressed state, thereby playing a buffering role in fixing the power distribution cabinet 1.

[0058] like Figure 7-10 As shown, an auxiliary mechanism 7 is installed in the lower groove of the quick release cylinder 53. The auxiliary mechanism 7 has a connecting column 71 inserted in the lower groove. The connecting column 71 includes an upper connecting body 75 provided at the upper end. The outer diameter of the upper connecting body 75 is smaller than the outer diameter of the connecting column 71 and forms a placement step. It should be noted that, as shown in FIG. Figure 6 As shown, an escape hole 423 is provided between the two sets of connecting beams 42. The diameter of the escape hole 423 is smaller than the outer diameter of the quick-release cylinder 53 and larger than the inner diameter of the lower groove, so that the quick-release cylinder 53 can overlap the two sets of connecting beams 42 to maintain stability, and the upper connector 75 can be inserted into the lower groove through the escape hole 423.

[0059] Contraction grooves 531 are formed on both sides of the bottom of the quick-release cylinder 53. A sliding post 58 is slidably mounted in the contraction grooves 531. It should be noted that a sliding block 57 is fixedly mounted on one end of the sliding post 58. The bottom end of the sliding block 57 is provided with an inclined surface 571. At the same time, the upper end of the sliding post 58 is provided with a horizontal surface 572. When the connecting post 71 moves from bottom to top, the top of the upper connecting body 75 will preferentially contact the inclined surface 571.

[0060] The side of the sliding column 58 that is away from each other slides in the inner wall of the quick-release cylinder 53, and a second spring 59 is sleeved on the surface of the sliding column 58. The two ends of the second spring 59 are respectively fixedly connected to the sliding block 57 and the inner wall of the contraction groove 531. When the sliding block 57 is squeezed, it slides toward the contraction groove 531, and the second spring 59 is compressed. When the external force is released, the sliding block 57 is reset under the action of the second spring 59. It should be noted that in the initial state, one end of the sliding block 57 is already outside the contraction groove 531, and a small part of the sliding block 57 is still inside the contraction groove 531. Therefore, when the sliding block 57 moves, it will not fall out of the contraction groove 531.

[0061] like Figure 7 and Figure 9 As shown, a first ring 72 is fixedly mounted on the top of the upper connector 75. The outer diameter of the first ring 72 matches the inner diameter of the through groove 56. A first arc 721 is provided on the first ring 72 to cooperate with the inclined surface 571. A first horizontal contact surface is provided at the bottom of the first ring 72 to cooperate with the horizontal surface 572.

[0062] Continue to refer Figure 9A second ring 73 is slidably mounted on the surface of the upper connector 75. The outer diameter of the second ring 73 is the same as that of the first ring 72. At the same time, a second arc 731 is provided on the second ring 73 for use with the inclined surface 571, and a second contact surface is provided on the upper part of the second ring 73. The second contact surface is also horizontally arranged and is mainly used to cooperate with the first contact surface. In the initial state, due to the action of gravity, the second ring 73 falls freely to the placement step. At this time, there is a certain distance between the second ring 73 and the first ring 72. When subjected to an external force, the second ring 73 is adapted to move upward. When the first contact surface and the second contact surface are in contact with each other, the first ring 72 and the second ring 73 are closest to each other. A third spring 74 is fixedly installed between the first ring 72 and the second ring 73. The third spring 74 is used to maintain the positions of the first ring 72 and the second ring 73 in the initial state. At the same time, a spring groove (not shown in the figure) is provided at the bottom of the first ring 72, so that the third spring 74 can be completely retracted into the spring groove, and the first ring 72 and the second ring 73 are in contact with each other.

[0063] When the power distribution cabinet 1 is not reinforced, the connecting column 71 has not been installed in the quick-release cylinder 53. At this time, personnel are required to install the connecting column 71. During installation, the staff only needs to hold the connecting column 71, align the upper connector 75 with the quick-release cylinder 53 and push it in. During the upward movement of the connecting column 71, the first ring 72 first contacts the inclined surface 571 and produces an extrusion effect on it. The sliding block 57 is retracted into the contraction groove 531 under the extrusion of the first ring 72. When the first ring 72 is completely entered into the quick-release cylinder 53, the first ring 72 is separated from the sliding block 57. At this time, the second Under the action of the spring 59, the sliding block 57 is reset. The staff pushes the first ring 72 into the quick-release cylinder 53 to release the connecting post 71. Under the action of gravity, the connecting post 71 will move downward, and eventually the first contact surface will contact the horizontal surface 572. The first ring 72 will overlap the sliding post 58. At this time, even if the connecting post 71 is subjected to a downward force, the first ring 72 will not fall out of the quick-release cylinder 53 due to the restriction of the horizontal surface 572 on the first contact surface. At this time, the lower half of the connecting post 71 protrudes from the quick-release cylinder 53, and the first contact surface contacts the horizontal surface 572.

[0064] like Figure 2-Figure 3 As shown, a threaded hole (not shown) is provided at the bottom of the connecting column 71, and a support mechanism 8 is installed inside the threaded hole. The support mechanism 8 is used to provide auxiliary support and fixation for the power distribution cabinet 1. The support mechanism 8 includes a vertical rod 82 threadedly installed inside the threaded hole, and a base 81 is fixedly installed at the bottom of the vertical rod 82. When the connecting column 71 is installed in the quick-release cylinder 53, the vertical rod 82 can be rotated to make the base 81 contact and abut against the ground, thereby supporting and fixing the power distribution cabinet 1.

[0065] At the same time, a nut 83 is threadedly installed on the upper end of the vertical rod 82, so that when the base 81 contacts the ground, the position of the vertical rod 82 is fixed by the nut 83;

[0066] A weight 6 is sleeved on the lower end of the vertical rod 82. The weight 6 can be placed on the upper end of the base 81 to increase the weight of the base 81, thereby increasing the stability of the switch cabinet 1. Because the weight 6 is heavy, the cantilever 22 will not move at will even if it is in a free state.

[0067] Furthermore, the base 81 can be configured as a magnet, and the weight 6 can be made of a magnetic material, thereby increasing the stability of the installation of the weight 6.

[0068] When the lock body 53 is in the unlocking state, the lock body 53 is unlocked, and the lock body 53 is unlocked, and the lock body 53 is unlocked, and the lock body 53 is unlocked, and the lock body 53 is unlocked.

[0069] Under the action of gravity, the connecting post 71 moves downward and escapes from the through slot 56 , thereby achieving the disassembly of the connecting post 71 .

[0070] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
